5 AWS Cost Optimization Tips Every Startup Should Know

Managing cloud costs is one of the biggest challenges for startups running workloads on AWS. Without proper oversight, your monthly bill can quickly spiral out of control. Here are five essential tips to keep your AWS spending in check.

Right-Size Your Instances

Many teams over-provision EC2 instances during initial setup. Use AWS Compute Optimizer to analyze your usage patterns and identify instances that are larger than necessary. Switching from an m5.xlarge to an m5.large can cut costs by 50% with no performance impact for many workloads.

Leverage Spot Instances

For fault-tolerant workloads like batch processing or CI/CD pipelines, Spot Instances offer savings of up to 90% compared to On-Demand pricing. Combine them with Auto Scaling groups for maximum flexibility.

Use Reserved Instances Strategically

If you have predictable baseline workloads, Reserved Instances or Savings Plans can reduce costs by 30-72%. Start with a one-year term to maintain flexibility while still capturing savings.

Enable S3 Intelligent-Tiering

For S3 buckets with unpredictable access patterns, Intelligent-Tiering automatically moves objects between access tiers. This eliminates the need for manual lifecycle policies while optimizing storage costs.

Set Up Billing Alerts

Configure AWS Budgets to receive alerts when spending exceeds thresholds. Early warnings prevent surprise bills and encourage proactive cost management across your team.

Start implementing these strategies today, and you will see meaningful reductions in your next AWS invoice.
